insert condition into JSP page.

hello experts.

i have a change password page as below:-
--------------------------------------------------
current password: --pass--
new password: --newPwd--
retype new password: --newPwd2--
---------------------------------------------------

after a user logs into the system, he/she is able to change password.

i've created a recordset, so that it will display the user's current password (--pass--) in the 'current password' field.

i've also did a 'server behavior-update record' thing so that the current password in the dB will be replaced by the 'retype new password' element.

now i need to put a condition in the page, so that the password will only be replaced if ('newPwd'=='newPwd2').

please help. thanks in advance
